- a silo,

. tured at a mill, or wherever the Ilun'iber yis available and which can be taken down' and shipped in comparatively small pieces to be again set-1 up at. the place of use with great certainty'gand facility.`

The silo is indicated in general at a, the barn at Int-he connectin passage at c, and eopening lthrough which access may be had to the silo.

The wall of' the silo is built of the usual tongue and. groove staves. The ends of the staves are reduced in thickness about onehalf as illustrated in the edge and sectional views of Fie.' 9, so that they will overlap 'ornii'ng'a rather deep salined joint, as 'indicated at 100. The ends o t` these staves are chainfered ott', slanting upwardly from the outer side of the stave as indicated lin the edge view of Fig. 9,so`that the line on which the ends of the staves join lone an- 'other is inclined from the outside and inside upwardly. Before the ends are put together theyare covered with white lead to seal the joint. In this way a joint is provided which Will prevent water or moisture from workvals 'along' the edge st-aves f inside or the in tol the outside of the. silo.

The'staves f which formthe sides of opening any grooved on their inner edges 'as at ff-aiid the doors g are rounded on ,their edges as at g to it in these grooves. Spacedl at interannular grooves` f* are cut to receive the hollow hubsfh" of.v i

These socket castings have transverse bores which have interior circiini-V :terential `grooves forming shoulders h2 to receive the shouldered endso'f therti'e-rods'z', the socket being provided with a removable cap j.- Screws le the base of the soc to hold these socket castings in position.- It' Eass through the :cap andv et castings into the staves will be seen that these socket castings by re'ason of their hubs entering the grooves inthe staves are held firmly against movement andI that the screws which fasten the vsockets to tlie staves are relieved of 'a lconsiderable amount of duty; that the tie-rod'sare sliouldered in the sockets so that 'they cannot v 'move lengthwise with respect thereto and are firmly held therein, constituting a rigidfspacing support for thestaves f which forni thev edges of the continuous opening.

I claimas my invention:

1. A silo having a .continuous opening from bottomy to top thereof, for said opening, ladder rounds extending across'said opening, sockets secured to the edge staves of said opening, tie rods secured in said sockets and .held therein against longitudinal movement, brackets secured at intervals'alongvthe edges of said opening -to receive and support said rounds, and connections including, a turn buckle between the door sections and the rounds.

Q; A silo having a continuous lo from bottom to top edges `of theed'ge staves of said opening beingV formed into a curved seat, sectional doors for said opening having curved edges fitting into the curved seats, socketsl secured t'o said edge staves of the opening, the rods having their ends secured in sa'id sockets against longitudinal movement, brackets senetherpart. of

They. are preferably round metal ,rods-extending around the silo at intervals Afrom top to bottom. I provide a compensating lugQfmade up of'a pair of' .identical oppositely directed tubularl memL bers 3 thfrough which the ,ends ofthe hoops pass.'A 'These tubularl ifn'einbers are chambered outlas at Li'to receive springs 5 which surround the ends of the hoops.v yThese hoops are" bent'- around the silo', the ends pass' .through the tubular members. 3 ofthe compensating lugs, the springs are slid on over the threaded ends of the hoops taking bear.-I ings against-the shoulder in the chamber 1i' y then tightened bydrawing. the' hoop irfnlyaround the silo an'd 'comressing the springs-by. means of t'ne nuts 4". The members are slightly tapered as at 3" to facilitate the manipulation an free action of the spring ends and said nuts 4. ',Ihe rearl face 32 of the lug is slightly curved to fit theeXterior-surface of the silo. If the silo expands the springs allow for4 expan. sion; ifthe silo contracts thesprings tak-e up 'anyloosenessingtlie hoops. Thus by the'use lof this compensating'lug the hoops 'are con-l tinually drawn tightly aroundl the silo in- In order to facilitate the putting onvof the hoops and ening their ends secured in the said Vsockets against from'dropping down I provide rings 7 which are suitably supported ced as on the depending wires 8, thehoops being passed" through these rings i ,The construe and' thus keptin alineinent." longitudinal movement. tion and support ofl these hoops is clearly In testimony whereof .afiX my signa- 'shofwnyin Iiig. 7 ture in presence of two witnesses.
